NCID9200 Digital Isolators

The NCID9200 by onsemi is a high-speed, dual-channel digital isolator designed to support isolated communications, preventing ground loops and hazardous voltages. Utilizing the pantented onsemi galvanic off-chip capacitor isolation technology, this device ensures high insulation and noise immunity, making it ideal for various industrial and automotive applications.

The NCID9200 is a galvanically isolated, high-speed, dual-channel digital isolator that facilitates isolated communications, allowing digital signals to transfer between systems without conducting ground loops or hazardous voltages. This patented device from onsemi leverages galvanic off-chip capacitor isolation technology and optimized IC design to achieve superior insulation and noise immunity. The thick ceramic substrate used in the capacitors provides approximately 25 times the thickness of thin-film on-chip capacitors and coreless transformers, combining the electrical performance benefits of digital isolators with the safety reliability of a >0.5 mm insulator barrier, similar to traditional optocouplers. Housed in a 16-pin, wide-body, small-outline package, the NCID9200 is designed for high-performance and reliability in demanding environments.
